This invention relates to improvements in lockers, andmore particularlyto the construction and the arrangement of the interlocking means forcontrolling the locking of one door by the operation of another door sas in garment lockers where separate hat and 1 coat compartments areassociated in pairs. In such lockers a key is provided for only one ofthe compartment doors which, when closed, holds the door of thecompanion compart ment locked.

.The main objects of the present invention are to provide a simple form.of interlock means for interconnecting the doors; to provide aninterlock which. maybe operated eitherby theouter edge or the hingededge of the door; to provide an interlockwhich may be easily installedin the locker and which is verystrongand durable in use. Two.illustrative embodiments of this 'invention are shown-in theaccompanying drawings, in which: V p

of a locker showing ,a section taken on line of- I the Wall- .of theframe.

The locker is preferably of sheet metal and 14, extending from the lowertransverse mempartments arelikewise respectively fitted with 1 doors 17and 18 hinged to the marginal frame 11 at opposite sides, so that theupper door 17 which is related with the lower door 15 swings to theright to open, and the upper door 18 which is related with the lowerdoor 16 swings to the left to open.

Theupper doors 17 and 18 are each provided with key operated locks forlocking the swinging edges of theidoor toe-the adthan the bar 19, shownat theleft, because it joining portion of the marginal frame; and

must. spanthe door 18 which is related with the coat door 16. In otherrespects the interlock bars are identical and a description. of

As is shown more clearly in Fig. 5, the up per and lower ends oftheinterlock bars have} flanges 21 which are slotted to receive sup,-

porting posts 22 whichv are rigidly carriedby. angle clips 23 riveted tothe outer frame 11.

The interlock bars are normally held in a raised position by means of acoil spring 24, which is anchored to a bracket 25, secured to Means areprovided forfsliding the bar downwardly against the action of springwhen the upper door is closed,.which consists of a cam or lug 26,. in-

tegrally formed on the upper end of the locking bar, which is engaged bythe edge of the corresponding hat door; ;At the lower end the bar'isbent; inwardly to provide a lug or finger 27 forengaging withthe latchbar 28 of the lower-door.v 1 In Fig. 2 the cam 26 is shown ascooperating with the hinged edge of the upper door 18;

but it may be arranged to cooperate with the Y swinging edge of a door,as is shownin Fig 6, as will be described hereinafter. The upper doorsare of sheet -metal construction,

with the flange 30 projecting. inwardly aroundtheledges, :which'isslotted as at 31,

see Fig. 8, to receive the cam portion. It will now be seen that whenthe door is swung closed, the sloping surface of the cam is engaged bythe upper side of the notch, and the interlock bar is thereby cammeddownwardly and held in that position.

The lower doors 15 and 16 are also of sheet metal construction, and themetal is bent around to form a tube 32 at the swinging edge. In thistube is slidably mounted the latch bar 28 which extends substantiallythe length of the door, and is provided with a handle 83, that projectsthrough a slot in the front wall of the door, so that the bar may bemanuallyraised or lowered, the movement of the bar being limited by thelength of the slot. Hooked catches, or keepers 34, are riveted to theouter frame 11, adjoining the swinging edges of the doors 15 and 16, andare bent into U-shape so as to project through slots 35 in the rear wallof the tubular portion 32, as is shown more clearly in Fig. 9. The latchbar 28 is slotted at'36 to receive the ends of the catches 34, as shown.The latch bar is cammed upwardly by the outer sloping end of the catch34 whenthe door is being closed, and drops down by gravity intoengagement with the hookin the catch to hold the door closed.

In Fig. 6 the interlock bar 38' is extended so that the cam 39, on theupper end, is engaged by the swinging edge of the top door 17 instead ofthe hinged edge of the door 18 as shown in Fig. 1. The cam 39 enters andis engaged by the upper side of the notch 31-in the flange of the door.In this form the cam is formed by bending over the upper end of the bar,while in the form shown in Figs. 1 to 5 the metal is bent out attheside. In either form, a sloping cam surface is provided for performingthe function of depressing the 100k bar.

At the lower end, the bar 38 is provided with the finger 27, and the baris slidably mounted on the locker wall in the same manner as describedfor the bars 19 or 20.;

As will be seen in Fig. 1 and Fig. 9, the finger 27-on the lower end ofthe interlock bar is in close relation with the upper end of the latchbar 28 when the door is closed and thebar is in the down position. This,of course, prevents lifting the latch bar of the lower door as long asthe corresponding up per door iscloscd and holding the interlock bardown against the action of the spring 22. When the upper door isunlocked and opened, the lock of the lower door may be then operated toopen the same.

In closing the locker, either door may be ;.closed while the other isopen. If the coat compartment door is closed first, the interlockbar isin the raised. position, under the action of the spring 24, and thefinger 27 is raised above the upper end of the latch bar when the baris, lifted: topass over the ends of the keepers 3%. The latch bar isthen shoved down to lock the coat compartment door, and when the hatcompartment door is closed, theinterlock bar is cammed downwardly andthe finger 27 is lowered and prevents the latch bar 28 from being lifteduntil the upper door is again opened.

In case the hat compartment door is closed first, the end of the latchbar when raised will strike against the finger 27, since the interlockbar is then in the lower position.

The upper end of the interlock bar is flexible and will yieldsuiiiciently to allow the door to be pressed shut. Then when the latchbar is shoved down to lock with the, keepers 34-, the upper end will.spring into place under the linger 27.

It is now manifest that a very simple and practical form of interlockhas been provided. The interlocking parts are easily mounted in place inthe locker; they occupy a very small space and do not interfere with theuse of the locker; and are not easily damaged or broken.

Illustrative embodiments of this invention have been shown anddescribed, but it will be understood that numerous modifications andalterations may be made without departing from the spirit of thisinvention as defined by the following claims.

I claim:

1. In combination, in a locker having two doors, an interlock barslidably mounted on the locker, said bar having a cam surface which isengaged by one of the doors to slide said bar into position to interferewith the operation of the latch of the otherdoor to prevent said otherdoor from being opened, and a latch forsaid other door.

2. In combination, in a locker having two doors, one of which has alatch, an interlock bar slidably mounted on the locker and adapted tointerfere with the latch'of the which is engaged by the other door inclosing so as to slide the bar into position to prevent the latch on theone door from being operated. 3. The combination in a locker, of acasing, two doors hinged on the casing to swing outwardly and arrangedone above the other, a keeper mounted in the casing'adjaccnt theswinging edge of the lower door, a latch bar slidably mounted on theswinging edge of said lower door and downwardly movable into cooperativerelation with said keeper, an interlock bar slidablymounted on thecasing and normally raised, said upper door and said interlock bar beingprovided with cooperating surfaces whereby when the door is closed, theinterlock bar is moved into position for locking relation with saidlatch ing sheet metal doors in superposed relation,

upper door for engaging the cam surface of the interlock bar so thatsaid bar is forced downwardly to prevent lifting said latch bar whensaid upper door is closed.

5. The combination in a locker, of casing, two doors hinged to thecasing and arranged one above the other, a latch bar movably mounted inthe swinging edge of the lower door, a keeper mounted in the casing, thelatch bar'being adapted to ride up'over the end of the keeper and dropdown into looking engagement therewith, an interlockbar slidably mountedin the casing, means on the upper door for engaging said interlockbarand shifting it into locking relation with said latch bar when saidupper door is moved toits closed position, and means for returning theinterlock bar when the upper door is opened.

6. The combination in a locker, of swinging doors in superposedrelation, a drop latch mounted in the swinging edge of one door, akeeper mounted on the locker-for receiving. said latch, and an interlockbar slidably mounted in the locker having a portion pro j ecting intoengaging relation with the latch and having acam portion projecting intothe path of the edge of another door so that the interlock bar is forcedinto position to prevent the latch from being raised when both saiddoors are closed.
